Abstract
The invention discloses a grain preservative film of modified-atmosphere packaging for rat control which contains capsaicin microcapsule. The film is prepared by components of polyethylene resin, polyvinyl acetate, zinc stearate, calcium stearate, light calcium carbonate, white carbon black, paraffin wax, antioxidant and fluorescent agent. The components are weighed and mixed proportionally, extruded by a single screw plastic extruder, and subject to blow moulding to prepare a film. Capsaicin microcapsule, as a raticide, is coated on outer surface of the plastic film by an adhesive to prepare grain preservative film of modified-atmosphere packaging for rat control. The raticide slowly and continuously releases, thus achieving objective of long-term effective rat control, and has bidirectional atmosphere modifying function on O2 and CO2, with good moisture permeability of small packages, good antifogging and antisweat performance and oxidation resistance and anti aging ability.
Description
Technical field
The invention belongs to the grain fresh keeping film, particularly a kind of special-purpose Flesh-keeping film (bag)-rodent-resistant air-conditioning preservative film for grain and preparation method thereof with the gentle conditioning function of protection against rodents.
Background technology
Agricultural products fresh-keeping has a lot of new technologies, for example preservation agent, preservative film etc. at present.All preservation agents and preservative film all are selectively to use to fresh-keeping object, and promptly the agricultural-food of different varieties will use the preservation technique of difference in functionality.Also do not have at present special at grain protection against rodents fresh-keeping preservative film or freshness protection package.
Summary of the invention
Technical problem to be solved by this invention is: a kind of rodent-resistant air-conditioning preservative film for grain and preparation method thereof is provided, adapts to the protection against rodents of grain, the use of controlled atmosphere.
Technical scheme of the present invention is: the special-purpose preservative film of a kind of grain rodent-resistant air-conditioning, it is characterized in that the prescription of its component film is, by weight,
By its above-mentioned component proportions except that Ratproof agent, batch mixes, after the kneading, adopt single-screw extruder to extrude, and the film of blowing formation; Wherein, Ratproof agent is evenly coated the plastic film surface behind blown film.
Rodent-resistant air-conditioning preservative film for grain, the optimal components of its blown film consists of:
100 parts of polyethylene master batches-polyvinyl resin PE
44～50 parts of properties-correcting agent-Vinyl Acetate Copolymer EVA
0.2 part of stablizer-Zinic stearas ZnSt
2.0 parts of stablizers-calcium stearate CaSt
Weighting agent-light calcium carbonate CaCO
31.0 part
Weighting agent-white carbon black SiO
20.5 part
Antioxidant-3,1,076 0.5 parts of 5-di-t-butyls-4-hydroxy phenylpropionic acid octadecyl ester
1.0 parts of fluorescent agents
0.4 part in lubricant-paraffin
In its mentioned component ratio batch mixes, after the kneading, adopt single-screw extruder to extrude, and the film of blowing formation; Wherein, Ratproof agent is a capsaicine, and capsaicine is made as microcapsule, and capsaicin microcapsule is evenly coated the plastic film surface behind blown film, and the best area of filming is 0.2～1.0g/m
2
Wherein Ratproof agent is a capsaicine, capsaicine is a kind of alkaloid that contains the vanilla acid amides, the natural capsicum element by capsaicine, two capsaicines, fall serial congener such as Dihydrocapsaicin, high Dihydrocapsaicin, high capsaicine family and formed, capsaicine has more than ten kind now, has strong sharp flavor and strong and stimulating most in the said capsaicine, therefore can be used as Ratproof agent, but capsaicine is easier to oxidation, if directly, very unstable as mediating one of material, so need be made into the microcapsule coating.
The illustrated capsaicin microcapsule of the present invention is the capsaicine that adopts after effective wall material wraps up.Selected wall material must be chemically stable, and can not damage the stability that the capsula interna thing is tired.As the low-molecular-weight epoxy resin class.Purpose is by the parcel capsaicine, forms microcapsule, slowly discharges in application process, makes air-conditioning preservative film have secular protection against rodents effect.Microcapsule and tackiness agent are miscible in together, immiscible material is evenly coated the film outside surface of above-mentioned blowing, the best 0.2～1.0g/m that adopts
2, in the tackiness agent content of microcapsule should consider capsaicine in the microcapsule concentration, smear quantity and tamanori intensity.Promptly get rodent-resistant air-conditioning preservative film for grain.
Making method of the present invention is: PE master batch and functional auxiliary materials carry out proportioning weighs and mixes, add single screw extrusion machine and blowing film forming after, the immiscible material of microcapsule and tackiness agent is evenly coated the film outside surface of above-mentioned blowing.
Advantage of the present invention is:
(1) has O
2And CO
2The two-ways regulation ability is carried out small packages when storage, can utilize the spontaneous controlled-atmosphere principle, adjustments of gas index effectively, and the optimum regime that makes it to keep relative stability reaches the result and the purpose of storage in controlled atmosphere;
(2) water vapour permeability is strong, antifog and the antisweat performance is good.
(3) performance and Stability Analysis of Structures have anti-oxidant and the anti-aging ability.
(4) Ratproof agent can slowly continue to discharge, and prolongs the working lipe of protection against rodents, and the protection against rodents effect is remarkable.
Below by the heatstroke prevention test explanation the present invention that bites:
Select 20 of 25～30gKM mouse, 5 in every cage amounts to 4 cages, and censorship protection against rodents film and the control film that grain is housed placed same position in the cage at random.Mouse freely drinks water, restrictive diet.Observe mouse activity, diet and sample by the situation of biting, observe 7d continuously.
The rodent-resistant air-conditioning preservative film for grain protection against rodents pilot survey result that bites
More than tried film and compare with the control film sample, the protection against rodents area discrepancy that bites is remarkable; Duration of test, it is normal to be tried the mouse diet, and activity does not have and poisons and death condition freely, belongs to standard state.The effect of biting of rodent-resistant air-conditioning preservative film for grain sample protection against rodents significantly.
